The link didn't show any listing.  I ran a site search for Alembic and didn't get anything that way either.  I then ran a search of all basses sorted alphabetically; no Alembics in the As.  Maybe it's already sold.

It has indeed sold.  I was going to take a look at it last night, but it's already gone.
